Sore hands, wrists, shoulders, back, all within 30 minutes... sounds like me when I first started riding a road bike, and I'm a dude. When there isn't enough core strength to hold the upper body up, that weight goes onto the hands. The other part is that with an aggressive fit, the rider is expected to ride hard most of the time, which takes weight off the hands. It's remarkable how my main road bike goes from feeling wonderful to hurt-y if I take it on a slow ride.
